Question

on the cursor line this error occurs.

Error:

Caused by: android.database.sqlite.SQLiteException: near ")": syntax 
error: , while compiling: SELECT value FROM system WHERE (name= ) ORDER BY name

The cursor looks like this:

 Cursor c = getContentResolver().query(Uri.parse("content://settings/system"),
 values, "name=", fields, "name");
    if (c != null) {
        c.moveToFirst();
        long lvalue = c.getLong(0);
        if (lvalue > 0) {
            m_ScreenSaverDelay = lvalue;
        }

Answer 1

Try this:

Cursor c = getContentResolver().query(Uri.parse("content://settings/system"), values, "name= '"+ theNameyouArelookingFor +"'", fields, "name");     

your query should evaluate to:

SELECT value FROM system WHERE (name='ThenameYouAreLookingFor') ORDER BY name
